Title: Production of nuclear fuel pellet
Inventor: MATSUMOTO TOSHIO
IPC: G21C3/62
Filed: 1990-06-21
Abstract: PURPOSE:To enhance the capacity of fuel by molding a pellet peripheral part and a pellet center part in different processes and unifying both of them to sinter the same. CONSTITUTION:A center region 2 is molded by mixing a TiO2 powder increasing sintering speed with a UO2 powder having high activity and pressing the resulting mixture to form a columnar molded body. An outer peripheral region 3 is molded by mixing an SiO2-Al2O3 powder with a UO2 powder low in activity and pressing the resulting mixture to form a cylindrical molded body. After the columnar molded body is inserted in the cylindrical molded body, the whole is again pressed to mold an integrated solid molded body which is, in turn, sintered in a reductive atmosphere. In the pellet thus constituted, since the crystal particle size of the center part of the pellet is large, time is required when a gaseous fission product is generated to reach a particle and the discharge quantity of said product to the outside of the pellet can be reduced. Since the crystal particle size of the outer peripheral part of the pellet is small and SiO2-Al2O3 is precipitated, creep speed can be increased by particle boundary slippage. As a result, the capacity in a high combustion degree region can be enhanced.
